By this I mean features that can possibly be applied via an update. For example I read in a few places that the OLED model will have bluetooth controller wake up (something that can only be done via wired MnK or Steam Controller). Or is this actually a hardware re-work with the internals?

Similarly I read that there will be wireless mic support from bluetooth headphones etc rather than being locked to the onboard mic on the deck.

To me these seem very software based but I could be very wrong.
